Reading A Sql Table And Writing To Another Sql Table?
Aug 22, 2010i need to read a sql table and insert all the records into another sql table in the same schema. It sounds dead simple but I've spent weeks trying different methods with no success.I'm using a datareader on the source table and a dataset on the target table. The program errors on the second iteration of the loop saying "@FunderAgreementNo" has already been declared. This is because I have the Parameter mappings contained in the loop (I think). I've tried moving this code elsewhere but then get different errors.

View 1 RepliesGet Datagridview Table Row When Datagridview Datasource Is DataTable?
Dec 8, 2010My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"

View 1 RepliesVS 2010 - Reading Cell Value From DataGridView?
Jun 26, 2010I'm reading a cell value from a Datagridview, and this works fine in other projects, but not here?
HTML
Dim OldGUID() As String = Nothing
Dim X as Integer = -1
For X = 0 To Me.DGView.RowCount - 1
If Me.DGView.Rows(X).Cells(0).Value.ToString IsNot String.Empty Then

Next
It fails on the line: OldGUID(X) = Me.DGView.Rows(X).Cells(0).Value
with: NullReferenceException was unhandled - Object reference not set to an instance of an object.
The Cell has a string value and during debug I see the value, but it fails anyway.
Produce Checkbox Column In DatagridView While Reading From Xml File?
Oct 6, 2010i am developing an application for generating xml file with some details inside and regenerating it whenever i need.Step1: In the user interface,i have placed a gridviewcontrol during run time. i used Datatable for building the table and assign this table as datasource to the datagridview control. last column("GHI") is a checkbox column and its is successfully viewable in the datagridview. the snippet is like this.
dim iDGVWCount as integer
iDGVWCount =1
Dim oDGVW As DataGridView
[code]....
Step 3: if i reopen this xml file and populate the celll details in datagridview, the column 'GHI' is not viewable as checkbox column. it is simply shown like an ordinary cell. the snippet for opening the xml file is shown here.
dim ds as dataset
ds = New DataSet
ds.ReadXml("C: estxml.xml")
[code]....
Question1 : is there any setting needs to be done for bring back this checkbox column automatically in the datagridview while reading from the xml file.
Question2 : how we can bring the value of unchecked column as false in the xml file. the node is included in the xml only if a checkbox is checked.

xmldoc.Load(openFD.FileName)

Currently I can only get the TITLE attribute values to show?

One To Many / Datagridview / Table Manager?
Dec 22, 2010 Made what I think was a tactical error by using lots of 3rd party controls that made it easy to get stuff going but resulted in carrying a lot of baggage with my apps. Now it is finally time to switch to VB.Net and I want to avoid 3rd party controls as much as possible.
The database is MS Access. Master table called GroupName, key GroupID, string GroupName. Child table is GroupCustomer, key GroupID+CustomerID. Two datagridviews, GroupName on top, CustomerGroup on bottom. I've studied the one to many videos and howto's and it is easy and works like a champ. Fill the tables, sort, filter, add, update, delete, all is well.
Top grid
GroupID1 GroupName1
GroupID2 GroupName2
and so on.....
[code]....
However, adding a third table is where I get into trouble. In the bottom grid I want to link customerID to the Customer table to pick up Name, address, city, state & zip for display purposes. I've modified the table adapter to create a select query returning the lookup data with the groupID and customerID. It displays nicely on the Fill but doesn't automatically refresh the customer lookup fields when I add or change a customerID and I can't seem to update new records or deletes. The only table in my query that I want to update is the GroupCustomer table but the query is not updateable.I've been trying to figure this out, read articles, learn, step back and think but am still stuck. how to use the controls that come with VS2010.
